Abstract
The increasing demand for good and improved polymeric composites has led to a surge in the number of researches on hybrid composites, strengthened and enforced with the natural fibres. This paper mainly analyses and presents the attributes of hybrid composites made from natural fibres and carbon nano-tube (CNT) nanoparticles. A novel hybrid composite considered in this research includes kenaf and coir fibres with CNT nanoparticles embedded in an epoxy matrix. The proposed hybrid nanocomposite’s elastic features are calculated by using different analytical models like Chamis, Mori-Tanaka, Nielson elastic models etc and also with the help of Representative Volume Element Analysis (RVE). The content of fibre volume is varied in four different samples and it is found that upon varying the content of fibre volume, the mechanical properties like longitudinal modulus and transverse modulus got affected. The results evaluated from different analytical models are observed to be in good agreement with each other and also with the results of RVE analysis.
对优质和改进的聚合物复合材料的需求日益增长,导致混合复合材料的研究数量激增,与天然纤维加强和强化。本文主要分析和介绍了天然纤维与纳米碳管复合材料的特性。在这项研究中考虑了一种新型的混杂复合材料,包括红麻和椰子纤维与碳纳米管纳米颗粒嵌入环氧基体。采用Chamis、Mori-Tanaka、Nielson弹性模型等不同的分析模型,并借助于代表性体积元分析(Representative Volume Element Analysis, RVE),计算了复合材料的弹性特性。通过对四种不同试样纤维体积含量的变化,发现纤维体积含量的变化会影响试件的纵向模量和横向模量等力学性能。不同分析模型的计算结果与RVE分析结果基本一致。
期刊介绍:
Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
